PA A 321 Contrails Q

Hello All..

Hopefully this hasn't been asked before.

I'm using FSX and I've got the Project Airbus A321IAE/CFM aircraft in there. Problem is that the contrails appear at right angles to where they should be...over and under the aircraft and not coming from the wings,,,,left and right,,,

IIRC, there's a 'sequence' (codes just need changing around) in the .cfg file for changing engine smoke (from FS9 to FSX) and I suspect that this might be the case for this issue too 

Any help please..tried the confusing PA Forum..no joy there. 

Thanks
